Cryptographic Services (CryptSvc) Defaults in Windows 10

Provides three management services: Catalog Database Service, which confirms the signatures of Windows files and allows new programs to be installed; Protected Root Service, which adds and removes Trusted Root Certification Authority certificates from your computer; and Automatic Root Certificate Update Service, which retrieves root certificates from Windows Update and enable scenarios such as SSL. If this service is stopped, these management services will not function properly. If this service is disabled, any services that explicitly depend on it will fail to start.

Default Behavior

Cryptographic Services is a Win32 service. In Windows 10 it is starting automatically when the operating system starts. Then the Cryptographic Services is running as NT Authority\NetworkService in a shared process of svchost.exe along with other services. If Cryptographic Services fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the CryptSvc service has failed to start due to the error.

Dependencies

Cryptographic Services cannot be started under any conditions, if the Remote Procedure Call (RPC) service is disabled.

While Cryptographic Services is stopped, the Application Identity service cannot be launched.

Restore Default Startup Configuration for Cryptographic Services

1. Select your Windows 10 edition and release, and then click Download.

2. Save the Win10_CryptSvc_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

The CryptSvc service is using the cryptsvc.dll file that is located in the %WinDir%\system32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.
